EE55 High Frequency Transformer Offline Flyback Transformers（Vertical）

Product Overview

The EE55 high-frequency flyback transformer is a robust magnetic component designed for medium-power switching power supply applications. Built with a ferrite EE55 core structure, it enables efficient energy transfer under high-frequency operation and provides reliable electrical isolation between primary and secondary circuits. It is widely used in AC/DC and DC/DC conversion systems, industrial power supplies, and inverter-based equipment.

Operating typically in the tens to hundreds of kilohertz range, high-frequency transformers like the EE55 are optimized for switching power topologies, where compact size, efficiency, and thermal performance are critical.
Compared to smaller core sizes, the EE55 structure supports higher power levels and improved thermal dissipation, making it suitable for applications requiring stable output and continuous operation.
